EMBALMlNG-SYRI NG E.

SPECIFICATION forming part of Letters Patent No. 425,134, dated April 8, 1890.

Application filed September '7, 1889. Serial No. 323.235. (No model.)

To all whom it may concern:

Be it known that I, THOMAS HOLMES, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Embalming-Syringes, of which the following is a specification.

My invention relates to apparatus for embalming the dead, and the purpose thereof is to provide an extremely simple and inexpen-- sive apparatus whereby any antiseptic preserving fluid of any suitable character can be injected into the arteries and veins by a continuous operation and under any required degree of elastic pressure.

To this end the invention consists in the combination, with an elastic expansible reservoir, of an eduction-pipe proceeding from the lower part thereof and having a suitable point and an air-induction pipe communicating with said reservoir and provided with a compressible air-bulb having suitable valves, whereby air may be forced into the reservoir to a suitable point of expansion and retained therein to exert an elastic force upon the fluid and force it gently and continuously into the tissues or into the arteries and veins, the compressing force being aided by gravity.

The invention consists, also, in the several novel features of construction and new combinations of parts hereinafter fully set forth, and then definitely pointed outin the claims which follow this specification.

To enable those skilled in the art to make and use my invention, I will describe the same in detail, reference being had to the accompanying drawings, in which- Figure 1 is a view showing the complete apparatus. Fig. 2 is a partial sectional elevation showing the valvular arrangement.

In the said drawings, the reference-numeral 1 denotes a flexible reservoir formed of a material capable of yielding under pressuresuch as rubberwhereby said reservoir may be expanded by internal pressure. Connected to the lower portion thereof is an eductiontube 2 of flexible material and of suitable length to permit the reservoir to be suspended at any limited height above the point of insertion or injection of the embalmingfluid. This tube is provided with a suitable point 3, and a small forcing bulb 4 may be com nected with said tube, if desired. This bulb is of substantially the same form and construction as the bulbs used upon enema syringes, and is similarly provided with checkvalves 5 and 6.

Communicating with the interior of the ex pansible reservoir is an air-induction tube '7, having a forcing-bulb 8, similar to the one upon the pipe 2, and provided with checkvalves 9 and 10, a separate valve 12 being placed at or near the mouth of the pipe in the reservoir to resist the tendency of the confined air to escape. A cook 13 is placed in the eduction-pipe 2, and a loop or strap 14 is attached to the mouth or top of the reservoir to enable it to be hung up upon a hook or nail. A suitable neck 15 is mounted on the top and provided with a screw-stopper or valve to permit the reservoir to be filled and prevent the escape of the air.

In use the reservoir containing a suitable quantity of embalming-fluid is hung upon a hook orother support at a height proportioned to the degree of pressure under which the fluid is to be injected. If the blood-vessels are weak and easily ruptured, care must be used in graduating the pressure to the ca pacity of the arteries and veins to resist it. The point 3 on the tube 2 is then inserted in the well-known manner, and the cook 13 is opened, permitting the fluid to flow through the tube. If greater pressure is required, the bulb 8 is operated to force air into the reservoir and expand the elastic wall of the same until the necessary degree of pressure is reached. The operation may be further assisted bythe action of the compression-bulb a, by which the pressure may be increased momentarily if circumstances require it. This construction and organization of parts constitutes a complete embalming apparatus, capable of continuous operation at any re quired uniform pressure, the whole being extremely simple, easily operated and regulated, and manufactured at a comparatively low cost. A rubber handle 16 may be added to the reservoir to enable it to be carried.

What I claim is 1. In an embalming syringe, the combination, with a flexible and elastic reservoir, of an eduction-pipe having a cock, an air-induction tube having a check-valve at its tion, with the expansible elastic reservoir 1, of the eduction-tube 2, having the point 3 and cock 13, the air-induction tube 7, and the bulb 8, having the valves 9 and 10, the reservoir being provided with the neck 15, having a valve or stopper, substantially as described.

In testimony whereof I have afiixed my signature in presence of two witnesses.

THOS. HOLMES.
